.\nother ohjeet is to provide :1 bolt and now] means for providing abinding aetion between the nut and bolt; in eonneetion with \\'ltl('llis :1 11o\el1nea11s l or lot-hing the binding produeing means.

()ther ohjeets and advantages will heap parent l'roni thel'ollowingdeser1pt1on. when t:1l\'tlt in eonneetion with theaeeo1upa1rving drawings.

ln the drawings: Figurel is :111 elevation ol'1n improved nut and bolt:loeking deriee. Fig 2 is a \ertieal longitudinal seetional viewtln-ret'hrough. l'ig. i is an end \'lt\\'.

ltel'erring partieulartr to the aeeo111pa11 ing drawings. i represents:1 bolt whieh is threaded praeti aily throughout its entire length. andi prmid d with a wreneh (ngaging head ll. The bolt is provided with abore throughout the length as indieated at 12, this bore being retlue das at. i i. said re dueed portionpassiug through the head H.

The opposite end of the '1olt is lfltffttl longitudinally to toriu the(lexihle set-tor i l lngaged on this kerl'ed end oi the hell is nut 15.

Extending hmgitudinaliy through the bore of the bolt is an expansionbolt to this bolt; being provided with a tapering head 17 whieh isarranged within the lterted end of the bolt. 'Ehe op osite end of theex- Specification of Letters Patent.

'ol' the l'aees ol' the Serial No. 817,601.

pausion holt extends through the smaller hore l-i where' it is providedwith a threaded portion to reeeive :1 nut 19 thereon.

Between the head 11 and the nut 19 is a washer plate 241 which is formedon one side with a pair of tongues 21, one of which is adapted to hebent to engage one of the side hues of the head It and the other bent inthe opposite direetion to engage against; one

nut 19. This will pre- \ent rotation of the nut 15) which would tend toloosen the expansion bolt andpermit; the nut 15 to he easily turned. Itwill thus he seen that ii) tightening the nut 19. the expansion holtwill he drawn longitudinally in the bore 12 to eause the tapered sidesof the head 17 thereof to bear against the sea-- nients it and l'oreethem outwardly into inding engagement with the nut; 15. The nut It)beingprevented froin rotation by the washer it! retains theexpansionbolt in roper position so that danger of accidental rotation' of the nut15 is eliminated.

'hat is elaiined is:

in a nut and bolt loeking device, a bolt l1:1\'itl L a longitudinal horeformed therethrough a head on one end of the bolt formed with :1 eentrallongitudinal bore eonnnunieating hut, of smaller diameter. the oppositeend of the bolt heing longitudinally kerted to-form resilien: set-tors.an expansion bolt disposed longitudinally through the said bores andli11\ ing a tapered head engagingthe sectors from within the bolt. theother end of the expansion holt heing threaded and provided with :1elaniping nut. and a washer between the out and head of the boltprovided with tongues heat against the nut and bolt head to preYentirotation of said nut.

in testimony whereof, I allix my signaure in the presenee of twowitnesses.
